GreenAlert
GA Series
 
    GreenAlert Product Family
GreenAlert general purpose alarms are outstanding solutions for applications that require general purpose local visual alarms and/or remote and programmable alarm capabilities. These innovative products are ideal for the economical retrofit of existing applications not equipped with alarm features and can even be used to bridge non-networked or non-alarmed devices to your RS-485 BACnet or Modbus BAS network. GreenAlert devices are perfect for control systems requiring alarming capability outside of a Building Automation System (BAS), or for LEED designs that require Outside Air Delivery Credit (EQC1) alarm requirements. GreenAlert devices monitor the analog output of other devices and generate local visual and remote alarms when preset limits are exceeded. GreenAlert products are available with simple fixed alarm thresholds or with fully programmable alarms for Low/High Limit with hysteresis or for dead band operation with upper/lower set points based on percentage of setpoint. GreenAlert devices are backed by a 12 month limited warranty.

   
empty   GA-50

Model GA-50 is a high quality, economical visual alarm/alert solution designed for new and existing applications where a visual alarm is necessary. The GA-50 includes a red LED alarm indicator housed in a durable UL94-5VA enclosure. Add the Model GA-50 alarm display unit to your product for visual alert/alarm capability, or retrofit existing control system alarm applications that require a visual alarm outside of the Building Automation System (BAS). This is particularly important for LEED designs in order to comply with Outside Air Delivery Credit (EQC1) alarm requirements.

  • Alarm Type: Visual

  • Alarm Input: 2 volt nominal (3V maximum) @ 20 mA

empty   GA-100

The GA-100 is a general purpose fixed threshold alarm device for new or retrofit applications requiring local and remote alarm options. Housed in a durable UL94-5VA enclosure, the GA-100 continuously monitors the analog output of another device and provides local and remote alarms when the alarm threshold value is exceeded. A red LED provides local indication of the alarm condition while a built-in relay provides remote alarm indication. The output can also be used to directly drive an external LED alarm.

  • Alarm Type: Local visual and remote alarm notification via Dry relay contact closure (30VDC/24VAC 3 Amps max) or Direct LED drive (15mA typical)
  • Alarm Input: 0-5V, 0-10V or 4-20mA with fixed 3.0VDC/6.0mA threshold

empty   GA-200-N

The GA-200-N is an advanced intelligent fully programmable alarm device with a built-in LCD display and RS-485 BACnet and Modbus connectivity housed in a durable UL94-5VA enclosure. The GA-200-N features selectable alarm types (Hi limit, Lo limit or Deadband with hysteresis), adjustable alarm setpoints and hysteresis; along with an advanced variable signal integration filter to minimize false triggering due to transient analog signal fluctuations. This feature is particularly useful in outside airflow applications affected by transient wind gusts. The GA-200-N supports analog signals of 0-5V, 0-10V, 2-10V and 4-20mA. Local alarm notification, selectable remote alarm relay contacts (N.O. or N.C.) and external alarm LED drive are all available from the GA-200-N.

  • Alarm Type: Local visual and remote alarm notification via dry relay contacts (N.O. or N.C, 30VDC/24VAC 3 Amps max) or direct LED drive (15mA typical)

  • Alarm Input Range/Threshold: 0-5V, 0-10V, 2-10V or 4-20mA with programmable threshold

  • RS-485 BACnet or Modbus Output
